Listed are ELISA Kits for the detection of Zonulin, an alias name of haptoglobin. The human protein, encoded by the gene HP, is 406 amino acid residues long and has a mass of 45,205 daltons. However, there are up to 2 reported isoforms. It is a member of the Peptidase S1 family. This protein is reported to have a secreted cellular localization, and is glycosylated. The gene is associated with Anhaptoglobinemia. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, primate, guinea pig, and other mammalian. This target may also be known as: binding peptide, haptoglobin alpha(1S)-beta, haptoglobin alpha(2FS)-beta, haptoglobin alpha polypeptide, zonulin, BP, and HP2ALPHA2.
